well, you can't be that picky if you're looking to buy used. lulz. those wheels are the spyder wheels--they don't come on the early z-06's, which is what your budget dictates. black was available all years iirc, jetstream blue (was my second choice), was not available until 2008. you won't find a low mileage (assuming less than 10k miles) for $40k.
good luck bro
